Super conductivity can be destroyed by_____________?
Correct answer: C. application of magnetic field
- A. adding impurities
- B. reducing temperatures
- C. application of magnetic field
- D. any of the above
Explanation
A magnetic field exceeding a superconductor's critical field disrupts its superconducting state and causes a return to normal resistance. Lowering temperature supports superconductivity, not destroys it.
